Petagram
A petagram (Pg) is a unit of mass equal to 10^15 grams or one quadrillion grams.
History/Origin
The petagram was introduced as part of the metric system's prefixes to represent extremely large masses, following the adoption of the International System of Units (SI). It is derived from the prefix 'peta-' which denotes 10^15.
Current Use
The petagram is primarily used in scientific contexts to quantify very large masses, such as in astronomy and geology, but is rarely used in everyday measurements.
Microgram
A microgram (µg) is a unit of mass equal to one millionth of a gram (10^-6 grams).
History/Origin
The microgram was introduced as part of the metric system to measure very small quantities, particularly in science and medicine, and has been widely used since the 20th century.
Current Use
Micrograms are commonly used today in fields such as pharmacology, nutrition, and chemistry to measure small amounts of substances accurately.
